CVE-2026-81004

Estado: RecibidaAlta (8.4)—

In the Linux kernel, the following vulnerability has been resolved:

ipmi:msghandler: Cancel work cleanly on an error

If an error occurs during startup of an IPMI interface, it may have scheduled work to run. The work needs to be canceled before the interface can be freed.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad local (AV:L/PR:N/UI:N) en kernel Linux con impacto en confidencialidad, integridad y disponibilidad. El fallo de cancelación de trabajo (work queue) puede permitir escalada de privilegios o ejecución de código en contexto del kernel.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
